Police say the servant is a 30-year-old woman, originally from Kenya, who managed to escape Tuesday and flag down a bus. A passenger helped her contact the Irvine police department.

Investigators say the alleged victim had contracted to work with Alayban’s family in Saudi Arabia in March 2012. Her salary was set at $1,600 a month, for working eight hours a day, five days a week. But once she arrived in Saudi Arabia, the servant says, her passport was taken from her. She also says she was paid only $220 a month and forced to work 16 hours a day, seven days a week.

Police say Alayban’s family traveled to the United States in May with the alleged victim and four women from the Philippines under similar contracts.

Armed with a search warrant, Irvine detectives and immigration and homeland security agents later found the four other women in the condominium, a news release from police and the Orange County District Attorney’s Office says. Police say all five women are in good health, and at this time, there are no indications of physical abuse.

Alayban is being held in the Orange County jail in lieu of $5 million bail. She faces a maximum sentence of 12 years if convicted.

This is the first forced labor human trafficking case to be prosecuted in Orange County under California’s Proposition 35, which passed in November and increased the penalty for human trafficking.
